I have heard Kent's turkey loads are pretty good. I've been meaning to order some to try at the range. Their "diamond shot" though is not Hevi-Shot or Tungsten. It's a lead pellet. They do make a Tungsten load (or did) I can't seem to find it on their webpage. They do have the waterfowl and upland game Tungsten loads listed though.
Ken, that was with my 1300 and the Tru-Glo choke tube. For #4's, that was a nice even pattern I thought. I could never get #4's to pattern worth a hoot!!
